Abstract

To develop a human interface for shape modeling of 3-dimensional (3D) objects, it is necessary to construct a “virtual workspace” where we can directly manipulate object models as in real space. We have proposed Space Interface Device for Artificial Reality (SPIDAR) for a virtual workspace. Using SPIDAR, we can operate in a virtual workspace with visual and force sensation. We have developed a rotating shape modeling system that simulates a turntable similar to that used for modeling clay. For real-time operation, we have considered object volume and have proposed an algorithm of high-speed and natural deformation model under the condition of constant volume.
